virtual void CBCGPEditCtrl::OnUpdateAutoOutlining ( int  nOffsetFrom,
int  nCharsCount,
BOOL  bRedraw = TRUE 

Called when the text in edit control has changed.

If auto-outlining is enabled, the framework calls this function every time the text in edit control has changed.

The default implementation uses the CBCGPOutlineParser to update the outlining information for the specified range.

nOffsetFromSpecifies the zero-based offset in internal buffer of the edit control. This offset points to the start of the update range.
nCharsCountSpecifies the number of characters, which defines the end of the update range.
bRedrawIf TRUE the edit control will be redrawn.
